i think the only instance of it being odd is in pulp fiction when tarantino himself is being confronted with having jules and vincent come to his home with a dead body and he says was there a sign out front that said dead nigger storage you can glean from that all you want his character was justifiably super pissed off he and jules were cool and hed used it before etc but i remember vividly being taken aback at its casual use in that specific setting every other time it has been in his movies it seemed simply historically or characteristically accurate
